TEXTILE MACHINE ATTACHMENT FOR WAXING YARNS AND THREADS.

Application filed August 22, 1922.

To all whom it may concern.

Be it known that I, WILLIAM EDWIN CAMPBELL, subject of the King of GreatBritain and Ireland, residing at Ashfield, near Sydney, New South Vales,Australia, have invented certain new and useful Improvements in TextileMachine Attachments for axing Yarns and Threads, of which the followingis a specification.

This invention relates to a waxing attachment for textile machinery, inparticular textile machinery in which yarns or threads are wound from ahank or cop onto a bobbin. Its object is to provide a means for automatically waxing yarns or threads to lubricate them uniformly butwithout applying a harmful. excess of wax to them, in order thereby tofacilitate their working in knitting machines and in other textilemachines.

Where yarns or threads are drawn over a pad of wax to apply lubricant tothem, irregular and unsatisfz-ictory results are obtained, as when thewax block is scored and furrowed the quantity of wax taken by the yarnor thread is insufficient, rubbing contact between the thread and thewax being then. accidental and more orless lost. The application of waxin this way is also ine-tticient as the yarn or thread is waxed alongone side of it only. Inconvenience and loss in time and material resultsfrom the consequent necessity for frequently changing the wax blocks orrolls and remo-ulding the worn I rejects.

In the attachment in which the present invention consists, the yarn orthread is drawn across the flat face of a disc of wax which is mountedfor rotation on a spindle or axle the centre of which is located to oneside of the course of the yarn or thread so that as the yarn or threadis drawn in contact with it under pressure sufficient to ensure lightrubbing contact, rotational move ment is applied to the wax disc and itis caused to'rub the yarn or thread helically and thus effectadistributed application of wax to it, whilst the wear on the wax blockwill be distributed and it will wear evenly to a disc stump. I

The attachment comprises a bracket adapted to be mounted vertically on amachine, a carrier arranged to slide freely in vertically disposedbearing guides in said bracket, a claw on said carrier carrying avertical spindle or axle, an inverted cup Serial No. 583,509.

mounted for rotation on said spindle or axle, said cup adapted to carrya cylindrical block of wax, a metal roller mounted for free rotation inthe carrier below the wax block, a quirl forward of said roller forguiding the yarn or thread, a knot breaker rearward of said roller inthe course of the yarn or thread, and a tension device with guide quirlbehind said knot breaker.

In the accompanying drawings,-'-

Fig. 1 is a side elevational view of the attachment, and

Fig. 2 is an horizontal section on the plane 22, Fig. 1.

:The bracket is formed with a bottom end shaped for mounting in a holeor seating in a fixed part of the textile machine in connection withwhich the attachment is used. The carrier 11 is freely slidable in thevertical guide groove 12 in the back of the bracket 10. The top end ofthe carrier 11 is bent forwardly at right angles and supports a spindleor axle 13, preferably fitted with a ball race 14 to form anantifriction mounting for the rotatable cup 15. 16 is a cylindricalblock of wax the edges of which are embraced by the circular lip 17 ofthe cup 15. 18 is a steel blade, which functions as a knot breakeradjust-ably mounted in relation to the flared slot 19 in the bracket 10.20 is an adjustable thread tensioning device of conventional type located directly behind the slot 19. 21 is a cylindrical beam rollermounted for free rotation on a ball race 22 carried on ahorizontal.spindle or axle 23 fixed in'a-n offset plate 24-. on the bracket 10. 25and 27 are guide quirls, and 26 is a yarn or thread in course ofmovement through the attachment. It is to be noted that the yarn orthread is wound twice over and once under the beam roller 21 (abouto'ne-a-nd-a half turns), in order to bring the thread twice into rubbingcontact with the bottom face of the wax block 16, and that the run ofthe yarn or thread is located to one side of the centre of the wax blockand not across the centre of it.

In operation, the yarn or thread 26 is drawn forwardly, up through thequirl 27 and tensioner 20, past the knot breaker 18, through the slot 19and around the roller 21. The wax block 16 rides freely on the yarn orthread above the beam roller 21, being held in rubbing contact therewithby gravity. The wax block 16 is caused to rotate by the frictionalcontact of the yarn or thread with it, and this rotational movementresults in a helical rubbing on of wax onto the yarn or thread so thatan effective serving is ensured. lVhen worn to a disc, the wax isremoved, the carrier 11 is raised up in its slide 12, and a refillplaced by pressing it into the embrace of the cup rim 1'7.

The wax cylinder is formed with a central concavity as shown in dottedlines in order to avoid formation of a stem as wear takes place.

lvhat I claim as my invention and desireto scour by Letters Patent is 1.A yarn and thread waxing machine, com iirising an horizontally mountedbeam roller, means for guiding yarn or thread to and from said roller, arotatable cup mounted for rotation about a vertical axis above saidroller and adapted to carry a block of wax, and a carrier for supportingsaid roller slidably mounted in vertical guides.

2. A yarn and thread waxing machine according to claim 1, characterisedin that the wax cup is located in tangential relation to the line inwhich yarn or thread is directed on the beam roller by its guides.

8. A yarn and thread waxing machine comprising in combination a support,a beam roller carried thereby, a wax holder mounted on the support anddisposed above the roller and adapted to carry a block of wax, and meansfor guiding a helical turn of thread around the roller whereby the blockis adapted to engage the thread at spaced intervals.

4-. A yarn and thread waxing machine comprising in combination, asupport, a horizontally disposed beam roller carried thereby, means forguiding yarn or thread to and from said roller, a vertically movablecarrier having a portion thereof overhanging the roller, an inverted cupshaped member rotatable within said carrier and adapted to carry a blockof wax, said block being adapted to engage yarn passing across theuppermost portion of said roller, and said block being normally urged bygravity into engagement with the yarn passing over the roller.

5. A yarn and thread waxing machine, comprising a bracket, a carrierfreely slidable in vertical guides therein, an inverted cup mounted forfree rotation on a vertical axis in said carrier, said cup adapted todetachably hold ablock of wax, a beam roller mounted. for free rotationbelow said cup on a horizontal axis out of alignment with the cup axis,yarn or thread guides forwardly and rearwardly of said beam rollerarranged to lead the yarn or thread over said roller tangentially to theaxis of said cup, and a tensioning device and knot breaker intermediatethe roller and the rearward guide.

6. A yarn and thread waxing machine comprising in combination arotatable holder adapted to carry a block of wax, a cylindrical rollerhaving the axis thereof extending transversely to the axis of theholder, said holder being so positioned with reference to the rollerthat the face of the wax adjacent the holder lies in a planesubstantially tangent to the roller, means for guiding a helical turn ofthread on said roller whereby the thread engages the wax at spacedintervals and means for operating the roller.

7. A yarn and thread waxing machine comprising in combination, a roller,a device rotatable about an axis transverse to the axis of the rollerand adapted to carry a wax block having a face extending parallel withthe most adjacent line of the roller, and so spaced with referencethereto that a thread passing over the roller will engage the wax, andmeans for so guiding the yarn that it may be wound helically on saidroller while passing beneath the wax.

In testimony whereof I aflix my signature,

lVILLIAM EDlVIN OAMPBELL.
